Overview of Analyzed Files

Basic stats on analyzed files

Intro

For analysis purposes we separate files in scope into several categories: main, test, generated, deployment and build, and other.

The main category contains all manually created source code files that are being used in the production.
Files in the main category are used as input for other analyses: logical decomposition, concerns, duplication, file size, unit size, and conditional complexity.
Test source code files are used only for testing of the product. These files are normally not deployed to production.
Build and deployment source code files are used to configure or support build and deployment process.
Generated source code files are automatically generated files that have not been manually changed after generation.
While a source code folder may contain a number of files, we are primarily interested in the source code files that are being written and maintained by developers.
Files containing binaries, documentation, or third-party libraries, for instance, are excluded from analysis. The exception are third-party libraries that have been changed by developers.

502 files

247 files

Main Code

All manually created or maintained source code that defines logic of the product that is run in a production environment.

The following criteria are used to filter files:

files with paths like ".*".

502 files match defined criteria (122,812 LOC, 100.0% vs. main code):

483 *.html files (117,138 LOC)
6 *.css files (2,592 LOC)
3 *.xml files (2,479 LOC)
6 *.js files (333 LOC)
1 *.py files (189 LOC)
3 *.rdf files (81 LOC)

" *.html" is biggest, containing 95.38% of LOC.
" *.rdf" is smallest, containing 0.07% of LOC.
